| 英文摘要 | Dendrimers composed of G1 (generation 1.0) polyamidoamine (PAMAM) and branched with poly (propylene oxide) (PPO)-poly(ethylene oxide) (PEO) were synthesized. The dendrimer series was characterized using Fourier transform infrared (FTIR) spectrometry, mass spectrometry (MS), H-1 nuclear magnetic resonance (NMR), and gel permeation chromatography (GPC). Results from surface tension and steady fluorescence measurements showed that the critical aggregation concentration (CAC) increased with longer PPO-PEO chains, while the microenvironment of solubilized pyrene became weakly polar. The size distribution of aggregates was examined using the dynamic light scattering (DLS) method, which indicated a narrow distribution and an average hydrodynamic radius (R-h) of around 100 nm. The effect of pH on this system was also investigated and showed that the length of amphiphilic branches played a large role in the protonation process. |
